Re: [Sip] SIPit 20 survey summary

["Frank W. Miller" <[e-mail]>]

Acknowledged.  However, if we're talking about adding messaging
infrastructure to SIP, then the discussion is quite relevant here.  I
for one would vote for a simpler mechanism than multipart MIME XML blah
blah blah.  With regards to Keith's comments, I would love to sit down
and provide an alternative proposal but I just don't have the time to do
it.  With all due respect, I'll implement whatever the standards
committee comes up with, but I don't think its unreasonable for me or
anyone else to express concern about protocol that is obviously designed
by committee and obviously more complicated that it probably has to be.
